What's the main threat facing frogs?
An infectious disease called Chytrid fungus is contaminating and wiping out frog populations in Australia and world-wide. It’s a disease that only affects amphibians because of their permeable skin (so it doesn’t hurt humans). The fungus attacks the parts of a frog’s skin that have keratin. It prevents them from maintaining a healthy balance of salts and electrolytes, resulting in a cardiac arrest. Since frogs use their skin to breathe, this fungus also makes it difficult for frogs to breathe.
Apart from disease, extreme weather events such as droughts and bushfires have put further pressure on wild populations. All these factors are a deadly combination that is contributing to the decline of many frog species.
